Title:
INDOOR NAVIGATION METHOD FOR HANDHELD TERMINAL, HANDHELD TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/219992
Kind Code:
A1
Abstract:
An indoor navigation method for a handheld terminal comprises: after an indoor navigation instruction is received, controlling a lens of a camera to obtain an image in a lens range, parsing bar codes (2) on bar code labels in the image, obtaining identification information of each bar code label and selecting colored blocks from at least two bar code labels according to a colored block selection rule (S10); computing coordinates corresponding to each selected colored block in the pixel coordinate system according to the position of each selected colored block in the image in the lens range; and computing coordinates corresponding to each colored block in the world coordinate system according to the associated data of the identification information of each bar code label and the coordinates corresponding to each colored block in the world coordinate system and the bar code label on which each selected colored block is located (S20); and computing coordinates of a handheld terminal in the world coordinate system according to a coordinate computation rule (S30). Also provided are a handheld terminal for indoor navigation, and a storage medium. By means of the present application, the real-time position of the handheld terminal can be rapidly and precisely computed, thereby improving the precision of indoor navigation.
